Salmonella enterica causes persistent intracellular infection while stimulating IFN-γ-producing CD4+ T cell responses (Goldberg et al., 2018), which, in turn, could produce IFN-γ to control phagosome infection and then bind to IFN-γ receptors on nearby infected phagocytes (Müller et al., 2012). The gene discussed is IFNG; the disease is infection.
